When I am driving, once my engine warms up, i start to smell coolant... i can smell it from in the car... there are no visible leaks under the car, there are no visible leaks in the passenger floorboard (where i was told it would leak if it were the heatercore)... i stop, pull over, pop the hood, and look & sniff and cannot find the leak... i do not SEE anything at all.... i smell it without turning on the heat/air... even w/ the windows up... could it be a hole in my radiator? i've replaced the water pump & gaskets already... and i've flushed and refilled the coolant...

HELP!

 

Try Auto Zone and see if they will rent or let you borrow a pressure tester.


That should help you pinpoint the leak.

Also look for tell-tale signs, such as weepage marks (white streaks) on the neck of the radiator.

You did not include a sig that shows your car year , but I remember seeing a bulletin talking about polishing the radiator neck to prevent weepage.

See here for '99's:
